“I contacted Ultimate Security to provide surveillance evidence for my divorce case. As you can imagine this was an upsetting period in my life and I’m grateful to Greg Kelly for his sensitivity and professionalism with which he handled my case. Due to his Police background he was able to save me time and money in supplying evidence which was both factual and legally admissible in court. I would have no hesitation in recommending Greg and his company to anyone unfortunate enough to find themselves in a similar situation.” - Ms S Davidson, Private Client (Yorkshire)
